Flags in the Nave (or Chancel, or Sanctuary)

Interesting article here on flags in church buildings. While I think that talk of “empire building” is rhetorical nonsense, the point about having the American flag (or a silly “Christian” flag; sorry!) in church buildings is well-taken. I understand that those flags can be sensitive issues, especially if they were provided by a member of the congregation who is a veteran. However, if they must be somewhere in the building, put them in the narthex or something.
This also goes with my opinion that Independence Day celebrations should not include many patriotic songs. Songs that are prayers for the country are good; “My Country ‘Tis of Thee” is not. This goes for the other side as well: “Amerika” bashing does not belong in the pulpit.
